AF 

1. (common) Stands for "as fuck".
2. (photographic) Short for autofocus. Sometimes combined with other letters, e.g. when talking about camera-side, AF-S is single autofocus (only done the moment you tell it to) and AF-C is continuous autofocus (done constantly between turning it on and off).

1. Dude, calm down, you got no chill and are angry AF!
2. What are you doing, shooting wildlife shots without an AF lens? Unless the animals are tranquilized, but then there's nothing interesting in that.
